For going from Ireland to Morocco it is a big journey. We had a few people that stop here to change their tires for Morocco. They told us next year they will rent a bike from us to go. It was to much boring and too long for nothing. But I think you have to experience it.
For weather, in january is very cold. Many road are close due to snow in the mountains.
But on the south it is nice during the day both cold at night like any desert conditions.
Finnaly it is the Rain season.
Not the best time to go. But it is very beautiful in any case.
If you need pre set routes with hotels suggestions let us know we have them in package.
Have a nice trip
